Newmar Braintrust info sharing - please:)!

I have a former workmate that is in the search for a retirement coach.

They have a 'desired' purchase budget of $200-225K (With some reserves planned for any catchup maintenance and or modifications.). They prefer a larger block engine, due to a trailer with Rock Crawling Jeep and other Sand Toys they plant to tow. Mountain Aire and on up the Newmar Food chain is their preference.

They have an uncle that had a Newmar Mountain Aire with dark paint and severe micro checking.

So question #1: What years did the micro checking phase out of being a concern in the Newmar model lines. If different, per model, and known - that would be good info.

Question #2: ISM, ISX of various HP and Torque capacities. On the ISX, what model years did the Newmar typically have ISX's that were beyond the CM87 (Or is that CM870?), potential at risk for #6 valve head problem?

Any concerns on any model years with the ISM?

Due to his Uncle's input, he's mostly interested in Spartan Chassis. Am I correct that depending upon year and model these will be either K2 or K3's?

Within his targeted budget range, are their model years differences to be aware of that would make one coach, and or chassis preferable then another.

And a more basic question in general, with that targeted budget range - what models and years would you recommend he drill down deeper on?

I'll note, that in our conversations. He has an opinion that if he can make the right case, with sound logic and reasoning behind it, to the Executive Review Committee (His DW!), he feels he could probably bump that budget up to the $250-275K. For those with the encyclopedic knowledge of Newmar's - is this enough of target price to open any other coaches with 'Well then this would get you...'?

They're not too hung up on length, and would consider any 40-45' Newmar, though his wife would prefer 42-44' (Funny how '45 foot!!! That's too big! syndrome seems to factor into this... But, she said she'd keep an open mind. And does understand that at the higher up the food chain of models, 45' is the norm - and thus more supply.)

Thank you for any thoughts or suggestions.
Best to all,
Smitty (SOB Owner!)

Regarding #1: The microcracking (also know as "sidewall checking") was due to substandard sidewalls installed for several years by many manufacturers including Newmar. Newmar offered to replace those sidewalls using a sliding scale, so even though the coach you may be looking at is in the "bad" range the sidewalls may have been replaced. Newmar will know this info, all you need to do is call them with the coach number.

I do not recall exactly the year the bad material was introduced, it may have been 2004. Newmar phased in the replacement good material over a period of several years ending in early CY2008, beginning with the high line (e.g. Essex, Mountain Aire diesel), then the DP's (e.g. Dutch Star) and lastly the gas powered coaches. Our Canyon Star (gas) was one of the last coaches produced with the defective material, it was made in Feb 2008. We had the sidewalls replaced in 2014.

There are many posts on this forum which will give you a complete history of sidewall checking, but I'm sure owners who know more about what year DP's and high line coaches are affected will respond to this thread.

Many thanks for the info. I'm familiar with the checking, as our 04 CC Allure has the Owen's Glass and is checking badly in the Dark Maroon paints... It was the risk years for Newmar that I was not up on... Appreciated the years ranges you provided above - that should help!

Best,
Smitty

I would suggest a mtn aire like this

https://www.rvtrader.com/listing/201...553-5009754423

The isx problems are with the 650hp engines. This coach has a puny 500 isx. Which is fine for your workmate
